Application filed Decemher,28,'19 01. Serial No. 86,961. (No model.)

To all whom it may concern: v

Be it knownthat I, ARTHUR M. BURNHAM,

'a-resident of Gardiner, in the county ofKen-f nebec and State 'of Maine, have invented certain new and useful Improvements in Mop- 1 Wringers; and-I do hereby declare the following to be a full, clear, and exact descripa: tion of the invention,such as will enable others skilled in the art to which it to make and use the same;

My invention relatesto an improvement in mop-wringers, the object of-the invention being to provide a device of this character with improved means for permitting a sufficient 'amount of elasticity, or give to the pressure of a roller to permit a tangled or matted part "of the mop to: be draw n between rollers without injury; Y I A further object is to provide improvements of this character which will be strong and durable, comparatively cheap to manufacture, and yet neat and attractive in appear ance and easy to operate.

With these objects in view the invention consists in certainnovel features of construction and combinations and arrangements of will now be explained. On opposite sides of the pail metal strips 2 are securedby rivets or other means,- an dare-preferably of "the operating mechanism,and extend'forward be yond the pail to prevent-upsettin g when pressure is applied to the treadle.

In the pail, at itsupper forward end, a roller 8 is mounted to revolve, its trunnions 4 at each end being supportedtin suitable plates 5, riveted to the inner face of the pail, and below this roller 3 and secured between its ends to the forward end of the pail is a guide 6 for the mop. This guide 6 comprises a strip of metal bent at two points between its ends and having its central flat portion secured to the pail, and the respective ends project parallel forward toward the center of the pail appertains :an d'are bent upward slightly just beyond the outer face of roller 4, as shown at 7, and then extend outward and are bent at an angle and diverge to and are secured to the sides of the 'pail. A rectangular treadle 8 is pivoted at its respective ends to the ends of strips 2 and extends around the forward end of the pail and is provided with a plate or step 9 to receive the'operators foot to depress the treadle when wringing a mop.

The roll'enframe 9 comprises a metal strip bent at two points between its-ends, forming a horizontal intermediate portion disposed over the top of the pail and to which a rollerbracket 10 is secured and carries a roller 11,

and the respective ends of the frame 9 are ,pivotally'connected to arched portions of the strips 2.; 'The respective side members of the treadle 8 are provided between their ends with studs '12, on. which the coiled central portion of springs 13 are mounted, one end of the spring projectingin one direction and attached to a hook-shaped lug 14,p ivotally connected to the strip 2 by means of a pivot-pin 14:. The other end of said spring extends in the oppositeldirection and is bent at right angles and'projectsin'to ahole in a link 15, the other end of which latter is pivotally'connected to the rOller-frame -Q. stood, as clearly shown on the drawings, that a spring13and its connecting parts are pro- It is of course to be undervidedon both sides of the pail precisely like that abovedescribed in connection with one side.

" The operation of my improvements is as 7 follows: When the operator desires to wring shape shown to permittheattachment of the the water from the mop, he places the mop :in the pail and the guide 6 serves to direct "the same against roller 3. He then presses 15 and treadle 8 that should the mop be tangled or matted this yielding or elastic connection will permit the tangled or matted portion of the mop to be drawn between the rollers without injury.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. In a mop-wringer, the combination with a pail and aroller mounted therein in stationary bearings, of a movable roller-frame, a roller mounted in said movable frame, a treadle, a link connected at one end to the movable roller-frame, and a spring connecting the other end of the link with the treadle and normally bearing on the treadle at its juncture with the link to constitute a stop for the latter.

2. In a mop-wringer, the combination with a pail and a stationary roller revolubly mounted therein, of a movable roller-frame carrying a roller, a treadle, a link connected at one end to the roller-frame, a spring coiled between its ends on a pintle carried by the treadle, a lug connected with the pail supporting one end of said spring, and the other end of said spring connected to the link.

3. In a mop-wringer, the combination with an angular pail, of strips secured thereto and projecting forwardly beyond the same, a stationary roller in the forward end of the pail, a roller-frame pivoted on said strips and carrying a roller, a treadle pivoted to said strips, a lug on one of the strips, a pintle on the treadle, a link connected at one end to the roller-frame, and a spring coiled between its ends on said pintle and having one end supported by thelug and the other end connected to the link.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ARTHUR M. BURNHAM.
